Abstract
A training apparatus and method of use for guiding and improving the forehand, backhand and other strokes of a table tennis player by forcing the hand travel in the correct trajectory to strike the ball. The apparatus includes a waist and a chest belt, or a wide belt, to position a vertical rigid rod support to which the training guide is mounted. The training apparatus includes a plate that can be adjusted via a universal joint. There are two universal joints between the plate and the vertical rod support strapped to the player's torso. The position, orientation and the angle of the plate can be adjusted by the player via the two universal joints as required. The training apparatus improves the paddle stroke trajectory by guiding the hand such that the ball is returned to the opposing player bouncing off the table.
Claims14
A training apparatus for a table tennis player comprising:
- a belt system, wherein the belt system is configured to be affixed to the torso of the table tennis player;
- a first support;
- a first support holder, wherein the first support holder is attached to the belt system, wherein the first support is operatively connected to the belt system via the first support holder, wherein the first support holder enables rotational and translational movement of the first support with respect to the belt system for adjustments;
- a second support holder, wherein the belt system comprises first and second belts, wherein the first support holder is attached to the first belt and the second support holder is attached to the second belt, wherein first support is operatively connected to the first belt via the first support holder, wherein the first support is operatively connected to the second belt via the second support holder, wherein the first and second support holders enable rotational and translational movement of the first support with respect to the first and second belts;
- and
- a guide plate, wherein the guide plate is operatively connected to the first support such that the guide plate is in a position and angle configured to be in front of an arm of the table tennis player to constrain forward movement of the arm of the table tennis player, thus enabling a proper arm stroke.
3 more elements
A universal joint for rotationally and translationally attaching a first support to a second support of a training apparatus for a table tennis player comprising:
- first and second clips placed on each other, wherein the first clip includes a first opening for receiving the second support, wherein the second clip includes a second opening for receiving the first support;
- wherein the first clip comprises:
- a constricting portion defining one of the first and second openings;
- a first member attached to the constricting portion and extending radially outwardly from the constricting portion;
- a second member attached to the constricting portion and extending radially outwardly from the constricting portion, wherein the second member is spaced opposite the first member by a gap, wherein the fastener extends through the first and second members, wherein movement of the fastener from the second position to the first position to tighten the first and second clips to each other causes the first and second member to move towards each other and constrict the one of the first and second openings, wherein the first member includes a first distal end, wherein the second member includes a second distal end that extends towards the first member and slopes away from the one of the first and second openings, wherein the first distal end of the first member engages an inner side of the second distal end of the second member, wherein movement of the second member towards the first member causes the first distal end to slide along the inner side of the second distal end thereby causing the second member to move radially outwardly relative to the first member to further constrict the one of the first and second openings;
- and
- a fastener, wherein the fastener fastens the first clip to the second clip, wherein the fastener may be operatively moved to a first position to tighten the first clip to the second clip to prevent the first clip from moving relative to the second clip and to constrict the first and second openings for preventing translational and rotational movement of the first and second supports, respectively, that may be received in the first and second clips, wherein the fastener may be operatively moved to a second position to untighten the first clip from the second clip and enable the first clip to rotate relative to the second clip and the first support to move relative to the second support.
4 more elements
A training apparatus for a table tennis player comprising:
- a first support configured to be affixed to a torso of the table tennis player;
- a second support rotationally and translationally attached to the first support;
- a guide plate operatively connected to the second support;
- a universal joint, wherein the second support is rotationally and translationally attached to the first support via the universal joint, wherein the universal joint comprises first and second clips placed on each other, wherein the first clip includes a first opening receiving the second support, wherein the second clip includes a second opening receiving the first support;
- and
- a fastener, wherein the fastener fastens the first clip to the second clip, wherein the fastener may be operatively moved to a first position to tighten the first clip to the second clip to prevent the first clip from moving relative to the second clip and to constrict the first and second openings to prevent translational and rotational movement of the first and second supports, respectively, wherein the fastener may be operatively moved to a second position to untighten the first clip from the second clip and enable the first clip to rotate relative to the second clip and the first support to move relative to the second support.
